"The mayor has been asked by the White House to do some official-type duties related to the president's visit,'' campaign manager Kyle Madden said. Madden said he did not know the details, but he expects the mayor to attend Obama's speech at Henninger High School.

Miner had been scheduled to attend a fundraiser Thursday evening in Skaneateles put together by a committee of supporters, Madden said. Miner faces two challengers, Alfonso Davis and Pat Hogan, in a Democratic primary Sept. 10.
